SILVER PX

SILVER air handling units feature a robust casing performance: air leakage L1(M), thermal transmission U1 (T2), thermal bridges TB2, and mechanical strength D1. Cover panels on the front and back have a panel thickness of 56 mm, other cover panels/inspection doors are 52 mm. Insulation with mineral wool that meets fire safety class A1. The direct-driven SILVER Wing+ fans, equipped with IE5 class EC/PM motors, provide uniform airflow and low noise levels. The fans are designed for high efficiency and can operate continuously in temperatures up to 40°C, with features for easy maintenance and vibration isolation. The supply and outdoor air filters are made from glass fibre, and the filter holder has a filter locking system designed for effective sealing (complies with the requirements for bypass leakage to Class ePM1 85% (F9)). Duct connections for sizes 004/005, 007/008 and 011/012 are circular and designed for connection to ducts with insertion joints fitted with a rubber seal ring. Units in size 014 and up have rectangular duct connections with a securely mounted connection frame for slip-clamp joint connection. The SILVER air handling units are certified by Eurovent.

The counterflow heat exchanger is as standard equipped with bypass dampers and heat exchanger dampers, including mounted damper actuators. The counterflow heat exchanger is available in two versions: Normal efficiency (MPE, Maximum Pressure Efficiency) and high efficiency (MTE, Maximum Temperature Efficiency) respectively. In the MPE version, the focus is on low pressure drop across the heat exchanger. In the MTE version, priority is given to high temperature efficiency.

Internal leakage between air streams conforms to the provisions of Ductwork leakage class L2. Controls for section defrosting and temperature sensors can be obtained as an accessory.

Casing externally: recycled and renewably produced steel, painted in Swegon grey metallic (RAL 9007). Casing internally: recycled and renewably produced steel, with Magnelis® surface treatment. The use of recycled and renewably produced steel in the casing leads to a significantly lower carbon footprint for the product. All surface treatments are C5. Insulation: mineral wool.

Available in multiple sizes and configurations. Duct connections can be circular or rectangular, with optional full-face end panels.

SILVER PX units size 035 and up are delivered in several transport packages and the heat exchanger section itself can be disassembled and re-assembled on site to simplify site access.

SILVER units are flexible and can be integrated into complex ventilation systems. Detailed planning data is available in AHU Design selection software. BIM files and AutoCAD and Revit plug-ins are available for early project planning support.

Units are delivered on pallets and can be split into sections for easier transport. Maintenance access is provided via hinged doors. Filters, fans and heat exchanger are easily accessible.

SILVER air handling units must be equipped with third party control functionality.
